Description

Inclusion Criteria:

• Participants must be myopic and require lens correction from -0.25 to -6.00 Diopter (D) with 0.25 D steps, in each eye.
• Participants must be correctable through spherocylindrical refraction and with soft spherical contact lenses to 40 letters (0.14 logMAR) or better (2 meters distance, high-contrast chart) in each eye.
• Participants must be free of any anterior segment disorders.
• Participants must be adapted soft contact lens wearers and willing to wear their study lenses for at least 8 hours per day at least 5 days per week on a daily disposable wear basis for approximately 3 months.
• Participants must be willing and able to comply with all treatment and follow-up/study procedures, as well as willing and able to refrain from using any other contact lenses or solutions other than those provided for the duration of the study.

Exclusion Criteria:

• Participation in any drug or device clinical investigation within 2 weeks prior to entry into this study (Screening/Dispensing Visit) and/or during the period of study participation.
• Participants who are women of childbearing potential (those who are not surgically sterilized or postmenopausal) are excluded from participation in the investigation if they are currently pregnant, plans to become pregnant during the study, or is breastfeeding
• Participants who have worn gas permeable (GP) contact lenses within the last 30 days or who have worn polymethylmethacrylate (PMMA) lenses within the last 3 months.
• Participants with any systemic disease currently affecting ocular health or in the Investigator's opinion may have an effect on ocular health during the course of the study.
• Participants using any systemic or topical medications that will, in the Investigator's opinion, affect ocular physiology or lens performance.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Kalifilcon A Daily Disposable Contact Lenses; Participants will wear Bausch + Lomb kalifilcon A daily disposable contact lenses for at least 8 hours per day at least 5 days per week for approximately 3 months. Participants will be provided with Bausch + Lomb Sensitive Eyes Drops for use as needed during the study and lens cases for return of worn study lenses to the Investigator at the end of the study.

Active Comparator: Biotrue ONEday Daily Disposable Contact Lenses; Participants will wear Bausch + Lomb Biotrue ONEday daily disposable contact lenses for at least 8 hours per day at least 5 days per week for approximately 3 months. Participants will be provided with Bausch + Lomb Sensitive Eyes Drops for use as needed during the study and lens cases for return of worn study lenses to the Investigator at the end of the study.	Device: Biotrue ONEday Daily Disposable Contact Lenses; Contact lens; Other Names: Bausch + Lomb Biotrue ONEday® Daily Contact Lens

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean logMAR Contact Lens Visual Acuity	Visual acuity (VA) will be reported as letters read correctly, and the letters read will be converted to logarithm of the minimum angle of resolution (logMAR) acuity. The participant will read rows of letters on a standard LogMAR chart until the participant misses 3 letters on a row with 5 letters. The total number of correct letters will be recorded. A decrease in the number of correct letters indicates a decrease in visual acuity. Acuity will be averaged across visits.	3 months
Proportion of Participants With Slit Lamp Findings Greater Than Grade 2	During an examination of both eyes without lenses, graded slit lamp findings will be assessed for each eye using Grades 0 (none), 1 (trace), 2 (mild), 3 (moderate), and 4 (severe). Using only the non-missing observations from all visits without imputation, each eye will be classified with respect to findings greater than Grade 2 at any visit (Absent or Present). Epithelial edema, epithelial microcysts, corneal staining, limbal Injection, bulbar injection, upper lid tarsal conjunctival abnormalities, corneal neovascularization, and corneal infiltrates will be evaluated.	3 months
